Get the DUImug. When you drunkenly dial your friends, ex boyfriends, parents etc. when you're shit-faced and you feel the need to let them all know that they pissed you off, or simply that you love em, bottom line you most likely won't remember aka "Dialing under the influence"
"On the way home from the bar last night I totally made a DUI to my ex and told him what an ass he was. I swore I was never gonna call him again, oops."
